Monitoring reactions under pressure poses many challenges. Often, it is impossible to see into the reactor or process because the required pressure necessitates using a metal reactor instead of glass. It is difficult to know when the reaction is complete, much less being able to characterize the reaction kinetics. The accumulation of an unwanted or hazardous species is not uncommon. Taking samples for offline analysis (i.e. HPLC, GC, NMR) can introduce air or moisture into the reaction which can poison catalyst or the samples simply do not reflect the concentrations of the reactive species in their natural environment.

ReactIR™ real-time in situ FTIR can provide a "molecular movie" of the chemical reaction under actual process conditions, including under high pressure. The functional group specificity of FTIR allows the simultaneous monitoring of many chemical species. Our range of probe technologies, specifically designed for pressure chemistry, allows reactions to be monitored to over 350 bar.

This webinar will outline the relevant probe designs and technology for monitoring reactions at elevated pressure. Several pressure chemistry case studies will be presented including reductions (hydrogenation), oxidations, carbonylations, hydroformylations and reactions in supercritical CO2. Schematics and pictures of actual installations will be reviewed showing some very common ways to interface our Comp™ probe technology into a process.
